Open core. Real margins.
Construction ERP partner program, built for SMB.
OpenConstructionERP is AGPL-3.0 and free forever.
Implementation, localisation, training and converters are commercial —
and partners keep up to 100% of services revenue.
Built for partners working with small and mid-sized construction
firms. No annual fees. No quotas.
Partner take · Year-1 + first recurring slice€15,150
Services are 100% yours.
DDC writes the open core and doesn't quote implementation work. Every
euro the client pays for partner hours, training or custom modules
stays with the partner. No clawback, no marketplace fee.
On commercial lines, the split is published. Localisation and cad2data
carry the highest partner share because that's where local work
actually happens.
Year-2 onwards: the same client pays an SLA / optimisation retainer.
A Founding partner keeps 30% of that for as long as the client
stays live (Active partners keep 25%). SMB volume compounds — ten live
clients ≈ €9k/year before any new work.
Which one are you?
Three reader profiles. Pick the one that matches.
You're a partner
BIM consultancy · ERP integrator · freelance dev · local SI
You sell implementation, training, custom modules. We share margins
(25–65%) on everything commercial and never compete on services.
€0 partnership fee at any tier.
You can run OpenConstructionERP for free — or hire a vetted partner for
production go-live, localisation and SLA. Three legitimate paths,
your choice depends on team capacity and risk appetite.
You build a connector, training pack or custom module and earn
45–65% on every commercial deal it touches. Listed in the marketplace
once your first artefact ships.
Side-by-side with partner programs you may be weighing against.

€0 annual fee. No headcount minimums, no certification gates, no quotas.
Just close deals when you have them — keep the margin when you do.
Founding Partner — 3 spots, no fee, enhanced rates from day one.
Founding Partners get the Founding-tier rate card from signing,
keep that rate for 12 months, and co-shape the roadmap. After
month 12, you stay on Founding rates as long as you have at least
one live client.
What you get:65% margin on localisation packs and cad2data converters,
55% on OpenConstructionERP commercial licences and CWICR, 30% recurring on
renewals, 100% on services, €0 fees ever, direct Telegram
with the core team, your logo on the homepage, co-authored case study
after first go-live — distributed through DDC's social channels
(tens of thousands of AEC professionals across LinkedIn, X and
YouTube).
What we ask: one pilot deal in 90 days and a public commitment
to AGPL stewardship. No headcount minimums. No certification gates.
Build the team you need when you need it.
Founding cohort
3 / 3
Three Founding Partner spots open. Each slot is one regional
integrator who joins on the Founding rate card from day one —
no fees, direct line to the core team. 0 claimed so far.
Onboarding takes 1–2 weeks. Founding cohort closes once 3 partners
sign or on 31 December 2026 — whichever comes first.
What you actually get on day one.
Three concrete things: a 30-day timeline, a ready-made toolkit, and
an honest map of where leads come from. No big promises, just the
kit and the wiring.
LinkedIn & X co-marketing post templates with our hashtag set
Updated quarterly. Partners get a private GitHub release feed —
new templates, decks and pricing land there as soon as they ship.
Where leads come from
Honest map of the funnel.
~60–70% · Your existing client base — partners who already serve SMB GCs / subs / QS practices have the warmest path
~15–25% · DDC inbound — directory listing routes enquiries to the closest partner
~10–15% · Social co-promotion — DDC amplifies your case studies, posts and webinars across LinkedIn, X and YouTube (tens of thousands of AEC followers)
Bonus · Joint webinars and conference co-hosting once you have one live client
We can't replace your sales motion in Year 1 — but we can amplify it.
Most first deals come from the partner's own network; DDC compounds
from there.
What we won't do.
Anti-promises are honest promises. Here's what stays off the table:
×
We won't run your sales for you. Year-1 leads come mostly from your own network. We help, but we don't replace.
×
We won't gate the marketplace. No certification fees, no listing fees, no pay-to-play tiers. List as soon as you sign.
×
We won't invoice your clients without your sign-off. Resold or referred — you decide per deal, not us.
×
We won't change rate cards mid-deal. New rates only apply 90 days after notice, and never to deals already in flight.
×
We won't quote services against you. DDC has a written commitment to never compete on implementation, training or custom modules.
×
We won't hide the pipeline. If we route an inbound lead to another partner in your region, you'll see it in the partner Telegram — no surprises.

You already sell Odoo, SAP or Oracle. OCERP slots in as the
construction-specific layer — same sales motion, same delivery team.
One agreement covers multiple countries.
How to apply.
Four async steps, about two weeks end-to-end. Mostly your pace.
Listed on partner directory, co-promoted on our social channels, eligible for lead share from inbound enquiries.
Roughly 1–2 weeks end-to-end. Most steps are async — minimal calendar blocking on either side.
Common worries.
Plain answers to the questions worth asking before signing anything —
ours, theirs, anyone's.
"What if you go out of business?"
The product is AGPL-3.0 open source. BOQ, BIM viewer, schedule,
AI takeoff — everything sits on GitHub under a licence we can't revoke.
If DDC disappears, your clients keep running, your contracts stay in
force, and you can fork and maintain it yourself.
"What if I don't close any deals in Year 1?"
You owe nothing. €0 annual fee, no quotas, no minimums.
You stay on the Active rate card indefinitely. Founding cohort
asks for one pilot in 90 days, but standard Active partnership
has no deal target.
"Can I exit and take my clients with me?"
Yes. Client contracts are between you and the client — DDC has no
claim on them. Clients can keep running the AGPL build with nothing
to renew. You'd just stop selling the commercial dual-licence and
regional packs.
"What if you change the terms later?"
Founding Partners keep signing-day rates for 12 months. All partners
get a rate guarantee on deals already in flight. New rates only
apply to deals booked after 90 days' notice.
"Show me the contract before I commit."
The agreement is a 6-page PDF in plain English. We send it after
the discovery call. No NDA required to read it. If anything looks
off, you walk away — half an hour spent, no obligation.
"What if my first client hates the product?"
They run the AGPL build for free, so the downside is your hours
and their time — not a five-figure licence locked in upfront.
If a Founding pilot fails inside 90 days, we run a joint
retrospective and help you unwind it.
Still have questions?
Ten of them, answered straight.
It's AGPL-3.0 — can my client really use it commercially without paying anything?
Yes. AGPL-3.0 permits commercial use, modification, and self-hosting. The
obligation is to publish derivative source code if you modify and
distribute or expose it as a network service to
third parties. For most construction firms running internally, no
obligation triggers. For SaaS resellers or OEMs, a commercial licence
removes the AGPL obligation entirely — that licence is one of the SKUs
partners sell at 45–55% margin.
Why would a client pay a partner if the software is free?
For the same reason a developer pays a builder when bricks are sold at the
merchant: assembling, sequencing, localising, validating, and
operating the system reliably is the work. The repo gives you the
bricks. The partner ships the building.
Will OpenConstructionERP compete with me on implementation services?
No. This is a written commitment in every partnership agreement.
DDC's three commercial product lines are OpenConstructionERP commercial
licences, CWICR (cost database), and
cad2data converters — plus localisation packs and core training.
Implementation services are 100% partner revenue. Where a strategic account
asks DDC directly, we route it to the closest qualified partner.
How do margins actually pay out?
Two models, available per deal: (a) resold — partner invoices
client at list, pays DDC the wholesale price, keeps the margin;
(b) referred — DDC invoices client, pays partner the margin
within 30 days of cash receipt.
What's the difference between a Founding Partner and an Active Partner?
Founding Partners are the first 3 signatories. They get the Founding
rate card from day 0 — no ladder climb, no fees, direct line to
the core team. Active is the standard partnership for everyone
else. Founding cohort closes when 3 partners sign
or on 31 December 2026, whichever comes first.
Do I need to be a developer or a software house to qualify?
No. The dominant partner profile is a BIM consultancy or
construction-tech integrator with one technical lead and one
delivery lead. We help you onboard a developer if you don't have one —
training is free for the first two engineers per partner.
What about CWICR — the cost database?
The community CWICR is free with the AGPL repo. The
commercial CWICR — covering 11 countries, 55,000+ items,
monthly updates, audit trail — is sold separately and resold by partners
at 45–55% margin.
Can I run my client on the free AGPL version forever?
Yes — and many will. Partners earn their margin on the four things free AGPL
doesn't deliver: production go-live, SLA support, localisation
packs, and AGPL-free commercial licensing for clients who need it.
How is this different from being an Odoo partner?
Three concrete differences: (1) construction-native product
(BOQ, IFC, schedule, AI takeoff) — no retrofit; (2) higher
margins — up to 65% on localisation packs and cad2data converters,
55% on commercial OpenConstructionERP / CWICR; (3) no annual
partnership fee at any tier; (4) DDC explicitly does not compete on
services.
What if I never close a deal — do I lose my partnership?
Nothing punitive. You stay on the Active rate card indefinitely —
there's no demotion, no fee clawback, no expiry. If activity slows,
we work with you on lead-share or co-sell. Founding partners keep
Founding rates as long as they have at least one live client.
